Xarchiver is a front-end to various command line archiving tools. It uses GTK+ tool-kit and is designed to be desktop-environment independent. Supported formats are 7z, ARJ, bzip2, gzip, LHA, lzma, lzop, RAR, RPM, DEB, tar, and ZIP. It cannot perform functions for archives, whose archiver is not installed.

This package provides the reference implementation of Brotli, a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. It is similar in speed with deflate but offers more dense compression.

The specification of the Brotli Compressed Data Format is defined in RFC 7932.

bzip2 is a freely available, patent free (see below), high-quality data compressor. It typically compresses files to within 10% to 15% of the best available techniques (the PPM family of statistical compressors), whilst being around twice as fast at compression and six times faster at decompression.

Archive huge numbers of files, or split massive tar archives into smaller chunks.

minizip-ng is a zip manipulation library written in C, forked from the zip manipulation library found in the zlib distribution.

Lhasa is a replacement for the Unix LHa tool, for decompressing .lzh (LHA / LHarc) and .lzs (LArc) archives. The backend for the tool is a library, so that it can be reused for other purposes. Lhasa aims to be compatible with as many types of .lzh/lzs archives as possible. It also aims to generate the same output as the (non-free) Unix lha tool, so that it will act as a free drop-in replacement.

QuaZIP is a simple C++ wrapper over Gilles Vollant's ZIP/UNZIP package that can be used to access ZIP archives. It uses Trolltech's Qt toolkit.

QuaZIP allows you to access files inside ZIP archives using QIODevice API, and that means that you can also use QTextStream, QDataStream or whatever you would like to use on your zipped files.

QuaZIP provides complete abstraction of the ZIP/UNZIP API, for both reading from and writing to ZIP archives.

Lzlib is a C library for in-memory LZMA compression and decompression in the lzip format. It supports integrity checking of the decompressed data, and all functions are thread-safe. The library should never crash, even in case of corrupted input.

unshield is a tool and library for extracting .cab archives from InstallShield installers.

FastJar is an attempt to create a much faster replacement for Sun's jar utility. Instead of being written in Java, FastJar is written in C.

7-zip is a command-line file compressor that supports a number of archive formats and features self-extracting archives.

Miniz is a lossless data compression library that implements the zlib (RFC 1950) and Deflate (RFC 1951) compressed data format specification standards. It supports the most commonly used functions exported by the zlib library.

Pbzip2 is a parallel implementation of the bzip2 block-sorting file compressor that uses pthreads and achieves near-linear speedup on SMP machines. The output of this version is fully compatible with bzip2 v1.0.2 (i.e. anything compressed with pbzip2 can be decompressed with bzip2).

GNU Gzip provides data compression and decompression utilities; the typical extension is ".gz". Unlike the "zip" format, it compresses a single file; as a result, it is often used in conjunction with "tar", resulting in ".tar.gz" or ".tgz", etc.

Blosc is a high performance compressor optimized for binary data. It has been designed to transmit data to the processor cache faster than the traditional, non-compressed, direct memory fetch approach via a memcpy() system call. Blosc is meant not only to reduce the size of large datasets on-disk or in-memory, but also to accelerate memory-bound computations.

CBOR is a data format whose design goals include the possibility of extremely small code size, fairly small message size, and extensibility without the need for version negotiation. These design goals make it different from earlier binary serializations such as ASN.1 and MessagePack.

This package provides a parallel implementation of gzip that exploits multiple processors and multiple cores when compressing data.

SfArkLib is a C++ library for decompressing SoundFont files compressed with the sfArk algorithm.

Zstandard (zstd) is a lossless compression algorithm that combines very fast operation with a compression ratio comparable to that of zlib. In most scenarios, both compression and decompression can be performed in ‘real time’. The compressor can be configured to provide the most suitable trade-off between compression ratio and speed, without affecting decompression speed.

Lziprecover is a data recovery tool and decompressor for files in the lzip compressed data format (.lz). It can test the integrity of lzip files, extract data from damaged ones, and repair most files with small errors (up to one single-byte error per member) entirely.

Lziprecover is not a replacement for regular backups, but a last line of defence when even the backups are corrupt. It can recover files by merging the good parts of two or more damaged copies, such as can be easily produced by running ddrescue on a failing device.

This package also includes unzcrash, a tool to test the robustness of decompressors when faced with corrupted input.

This library allows reading and writing gzip-compressed JSON catalog files, which can be used to store GPG, PKCS-7 and SHA-256 checksums for each file.

minizip-ng is a zip manipulation library written in C, forked from the zip manipulation library found in the zlib distribution.

unrar-free is a free software version of the non-free unrar utility. This program is a simple command-line front-end to libarchive, and can list and extract not only RAR archives but also other formats supported by libarchive. It does not rival the non-free unrar in terms of features, but special care has been taken to ensure it meets most user's needs.

XZ Utils is free general-purpose data compression software with high compression ratio. XZ Utils were written for POSIX-like systems, but also work on some not-so-POSIX systems. XZ Utils are the successor to LZMA Utils.

The core of the XZ Utils compression code is based on LZMA SDK, but it has been modified quite a lot to be suitable for XZ Utils. The primary compression algorithm is currently LZMA2, which is used inside the .xz container format. With typical files, XZ Utils create 30 % smaller output than gzip and 15 % smaller output than bzip2.
